ICD-10 Code D35.6 – Benign neoplasm of aortic body and other paraganglia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D35.6 – Benign neoplasm of aortic body and other paraganglia
What it is
D35.6 identifies a noncancerous tumor arising from the aortic body or other paraganglia. Use it when the record documents a benign paraganglionic neoplasm, not a malignant or unspecified mass.
Clinical signs
Clinical features vary; refer to documentation. These tumors may be found incidentally or after evaluation for a neck, thoracic, or abdominal mass, and symptoms depend on location and hormone activity.
When to use this code
Use D35.6 when the provider clearly documents a benign paraganglioma, aortic body tumor, or other benign paraganglionic neoplasm. It also fits postoperative or follow-up documentation when the diagnosis remains benign and confirmed. If the site or behavior is unclear, check documentation before coding.
Do not use for
Do not use this code for malignant paraganglioma, unspecified neoplasm behavior, or a mass without a confirmed benign diagnosis. Check documentation if the lesion is described only as suspected or pending pathology.
Coding tip
Code from the pathology or final provider diagnosis, and verify whether the tumor is benign, malignant, or unspecified before assigning D35.6.
